Qualifications

• Bachelor's degree in Electrical/Computer Engineering or related field.
• 510+ years of embedded firmware development experience.
• Demonstrated hands-on experience implementing or tuning closed-loop digital control for a power converter, inverter, rectifier, or comparable power-electronics system.
• Strong proficiency in C/C++ for embedded systems development.
• Experience with microcontrollers, DSPs, ARM-based processors, or real-time embedded platforms.
• Practical understanding of PWM switching, ADC sampling, real-time control-loop timing, and digital control implementation.
• Experience debugging embedded control systems integrated with hardware and validating performance through instrumentation.

Responsibilities

• Embedded Firmware Development: real-time control for AC/DC and DC/DC power conversion stages.
• Design and optimize control algorithms for converters, inverters, rectifiers, and related systems.
• Develop firmware using real-time embedded architectures and MCU/DSP platforms.
• Support firmware verification, validation, debugging, and performance optimization.
• Develop and tune digital control algorithms for switching power converters (current, DC-bus voltage, power, transient response).
• Implement real-time control functions using MCU/DSP peripherals (ADC sampling, PWM, interrupts, timing).
• Analyze converter dynamics and stability (compensator design, bandwidth, phase margin).
• Support hardware bring-up and validation using test equipment and automated systems.
• Collaborate with design leads to validate performance against models and measured hardware.
• Develop safety state machines, fault protection coordination, and restart interlocks.
• Support parallel operation, module coordination, and current/power sharing.
• Implement droop regulation on AC and DC.
• Develop and maintain Modbus interfaces and other protocols (CAN, Ethernet, TCP/IP, RS-485, UART, SPI, I2C).
• Assist integration with HMI, supervisory controllers, and cloud interfaces.
• Participate in design reviews and create test procedures and documentation.
